AoE'rYLnNE-LAMP.

To all whom t may concern.'

Be it known that I, FRANK GUY, a citizen of the United States, residingat Springlield,Vv

in the county of Sangamon andState of Illinois, have invented a new anduseful Acetylene-Lamp, of which the following is a specification. f

Ther invention relates te lamps of the type which comprise ahorizontally dis-posed carbid box and a horizontally disposed waterreservoir having gas-tight connection with.y

the carbid box, and which employ distributers or sheets ofvfibrousmaterial adapted s to diifuse moisture on substantially the entire areaof one end ofthe vmass of carbid in the carbid box.

The present invention is a modificationy and improvement of.theinvention set forth in my application. SN. 780,274, acetylene lamp,iled July 21, 1913.l

The purposes of the invention are: toprovide simple and effective' meansadapted 'to keep the distributers in place in the carbid box and adaptedto prevent the drying out of that part of the distributing disks whichis not in contact withthe mass of carbid in the box; to increase thecapacity of the gas chamber lof the lamp; to provide means adapted toprevent extinguishing of the iiame by the concussions of. shot-firingand to provide in conjunction with a burner tube located above thehighest attainablel level of the spent carbid in the carbid box andequipped with filaments, means adapted to supply dry gas to the burnertube and thereby avoid fmoistening the filaments.

The invention is illustrated in the annexed drawing towhich reference ishereby made,

and will be. hereinafter particularly .de-k

scribed, andthe novel i'eatures thereof will befinallyrecitedin theclaims.

ter reservoir 3 Jfrom the carbid box 8. An

opening 4 in the partition y2 intercommunicates between the interior ofthe reservoirr 3 and the carbid box 8. f, f

The shell 1 has screw threads 24.

The cap 12 has screw threads l25 adapted to rengage on the screw threads24.`

A` gasket 13 surroundsthe shellv and the c apscrews down onthe gasket toJform a gas tight connection of the cap with the shell.

.A short pipe 21 isA rigid on the shelll and water may .be'pouredthrough the pipe intothe reservoir.

@A cap 2.2 has a hinge connection withithe pipe andisiitted in its upperend. The cap 22 has vents 23 through which any gas `entering thereservoir may escape to the atmosphere.

The dome 14 is rigid on andextendsupf wardly beyond the periphery offthe.shell and the axis'offthe dome is preferably at right angles to theaxis of the shell. lThe of accumulating an unusuallyl large volume ofgas in the chamber, which serves to maintain even pressure in the burnertube, notwithstanding anyusual inequalities in the generation of thegas.

- 'A fibrous disk, -or a series of parallel fibrous'fdisks 5,.preferablv of blotting paper, may be connected with the plate 6 ashereinafter describedand are adaptedto absorb water from the reservoirand diiiuse it von the end wall of the mass of carbid.

The disk holder consists cfa circular thin and flexible-metal plate 6,having an open-- ing 901i a height somewhat greater than the depth ofthe usual charge of the carbid 10. The plate 6 has integral 4fingers 27adapted to be bent to bear against the fibrouswdisks to connectthem withthe plate'. VIf the disks become clogged and it be desired to removethem vand substitute clean disks, the fingers may be prieol` away fromthe disks, the clogged disksinay be removed, fresh disks j may be placedon the plate and the ngers may be again pressed against the l.disks tohold them on the plate, and this procedure will be repeated each timethat it is desired to change the disks. The plate 6 serves to cover andprotect the disks.

In practice it has been found that if unprotected disks of the samediameter as the inside of the ycarbid box be used in contact withsubstantially the entire area of the end wall of the mass of carbid theheat of the A gas in the carbid box will dry out that part of-the diskswhich is above the carbid and causedry spots through which gas from thecarbid box may pass through the disks, downward along the face of thepartition 2 and through the opening 4 into the reservoir 3 and'thence tothe atmosphere, resulting in waste of gas The plate 6 prevents 'withrespect to the -dome and extends in wardlyto :about thecenter of thedome.

- [The burner tube 16 is fitted to the interior ofthe sleeve sothat when'the tube is pushed into the sleeve itV will be in gas tight con#nectionwith'the sleeve. The burner tip 17 is fitted in the usual mannerin the outer end of the tube. The reflector 18 is connected with thetube'16 by'a set screw 28.

' j' Thesleeve 15 supports the burner tube 16 1` in a horizontalposition so that the flame at the burner tip will be projectedhorizontally forward, and so that the back of the'refiector mounted on'the burner tube may 'lie close to the periphery of the shell, thuscontributing to the compactness and perfect balance of the lamp as awhole. The burner and the reflectorbeing above and close to thel lampbody'it protects them fromaccidental injury.

vvIn practice it is found that the horizon-` tally projected flame i'smuch superior to a verticallyprojected flame because the horiy zontalflame does not vproduce the rising and falling shadows whichresultvfrom'the fluc-A tuations of a vertically projected flame and ofgasthrough the tube'.

which are very annoying andv confusing to the user of the lamp. v

Filaments20, preferably of jute, voccupy the interior of the tube andcontrol the flow The friction of gas on the 'filaments 20 prevents thegas from going so far inward as to admit of extinguishing the flame bytheV concussione of shot-firing. If the gas pressure in the chamber B isstrong, `a sufficient number of filaments will be used to obstruct thetube sufliciently to prevent the gas from flowing too rapidly throughthe tube and blowing Y out through the burner tip and extinguishing theflame. If there is less gas pressure in the chamber B a less number offilaments will be used in the tube, so that the flow ofv the gas throughthe tube may not be unduly obstructed. In addition to controlling theoutflow of gas through the tube, the filaments serve to prevent inflowof gas under the concussions of shot firing. 1n other words, thefilaments prevent excessive outward flow and consequent .wasting of gas,and also prevent such sudden inward flow of the gas as to cause theextinguishing of the flame by the concussions of shot firing. Theaggregated .filaments serveas a lter and pressure controller lfor theoutwardly flowing gas and serve vin conjunction with the gas occupyingthe interstices between the filaments to forma gas cushion effective toprevent such rapid inflow of gas as would cause theextinguishing of theflame.

In practical use a disk or disks will be placed in the holder 6 and itwill be placed in the carbid box in close contact with the partition v2,and the spring 7 will be pressed against the holder `to keep it in'`place; a suitable .charge of carbid-will be'put in the box 8 and the cap12'will be screwed'down Y i onto the gasket .to make a gas tightconnection of 4the lcap with the shell; suchnumber of filaments 20 asare deemed suflicient will beplaced in the tube16, and the burner tipwill be placed in the outer end of the tube; a sufficientf quantity ofwater will be pouredv through thepipe 21 into theV reservoir 3 and thecap'22 will be pressed into the end lof the tube; the water will seepthrough the disk, ror disks, and will be diffused on the end wall ofkthe'mass of carbid and the generating of gas will begin. If `thegeneration of gas is too slow,'.a disk or disks will be removed topermit more rapid dis-` tributi'on of the water; or ifv the generationof' gas is too rapid, aA disk or disks will be added to' yretard. thedistribution of the water and thus diminish the generating of gas. Theblotting paper disks f4 givev` quick and even distribution of waterandare not easily injured or destroyed by the'carbidf; waterin contactwith one disk `is readily' diHused through all the disks contained Vinthe holder and is uniformly appli'edover substantially the entire lareaof the end wall of the mass of carbid. x

The associated disks constitute a barrier roo between the water inthe'reservoir 3 and the gas in the chamber 8 and the adding ofv a diskor disksv will augment the barrier to an 'extent sufficient to causeincreased gas pressure in the chamber and when the augmented barrier issaturated it will `more strongly oppose the passage of gas through thebarrier, with the result that while the gas pressure in the chamber isincreased, said increased pressure is effectively opposed by theaugmented and saturated barrier so that gas will not be forced backthrough the water in the reservoir.

If the pressure in the chamber B is s0 great as to cause the gas to blowout through the burner tip and extinguish the flame, the tube 1G will bewithdrawn and a sufficient number of additional filaments 20 will beplaced in the tube, and the tube will be replaced in the sleeve. If thepressure in the chamber B is found insufficient to force the gas outwardthrough tube, a suflicient number of filaments will be removed to permitproper outflow of -gas through the tube. When the diffusion of waterthrough. the disk or disks is properly controlled, as described, and theproper number of fibers are in place in the tube 16 the flowof gas inthe tube will be practically .uniform .and if a shot be fired the fiberswill oppose pulsation of the gas and prevent the extinguishing of theflame.

If gas blows out through the vents 23 when there is proper pressure atthe burner tip, ythe mass of disks I may be increased suiiiciently tostop kthe backward flow of gas into the reservoir 3. It will be seenthat the filaments 2O and the saturated disks 4 co-act to control thevgas pressure at the burner tip and to avoid thewaste of Vgas through thevents 23.
